Which statement best describes the process of science?
Scientists are objective and free of prejudice.
Generally, scientists work independently and discover new ideas without the help of others.
Scientific ideas evolve or change over time.
New ideas in science result from planned and well-designed experiments.
Which term describes a statement referring to a particular person's feeling, thought, judgment, belief, or estimation?
Fact
Opinion
Observation
Inference
The reason a fire truck’s siren sounds higher in pitch as it approaches you is because the truck pushes the sound waves together so that the sound wavelengths in front of the truck get shorter. This causes
frequency to increase which increases the pitch.
velocity to decrease which increases the frequency.
frequency to decrease which decreases the pitch.
wavelengths to elongate increasing the pitch.
The frequency of a wave can be calculated by
multiplying the velocity times the wavelength.
dividing the speed by the wavelength.
multiplying the amplitude by the wavelength.
dividing the frequency by the velocity.
A pot is made out of aluminum, but its handle is plastic. Why are these materials used in this way?
Aluminum is a conductor of heat, which allows the pot’s temperature to increase rapidly, while plastic is a heat insulator, preventing rapid heat transfer and keeping the handle cool.
Plastic is a heat conductor, which allows heat to move quickly out of the handle, keeping the handle cool, while aluminum is a heat insulator that holds the heat within the pot.
Both aluminum and plastic are heat conductors that allow heat to be transferred throughout the pot.
Both aluminum and plastic are heat insulators that keep the heat contained within the pot.
If one part of a solid object is at a higher temperature and another part of the same object is at a lower temperature, the heat is transferred within the object through the process of
Convection
Conduction
Insulation
Radiation
